MILKING APPARATUS, i

Application filed September 5, 1914. Serial 119860.430.

To all whom it may concern Be it known that I, AUGUST W. ZERATSKY, citizen of the United States, residing at La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Milking Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable, others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to milking apparatus, and more particularly to that class of milking apparatus adapted to be operated by mechanical suction.

The primary object of this invention is to provide a device adapted to be used in connection with such apparatus in order to increase the efliciency, durability and sanitary application thereof.

A further object of the invention is to provide an automatically operated valve for milking machines of the character set forth.

With these and other objects in view, as will hereinafter appear, this invention consists in the peculiar arrangement and 005p erative combination of the various related parts of a milking apparatus as hereinafter set forth and more particularly pointed out in the appended claims.

Referring to the drawings, forming a portion of this specification, and in which similar reference characters indicate similar parts wherever usedz Figure 1 is a view of the device as applied to the complete apparatus. Fig. 2 is a vertical section through the device; and Fig. 3 is a detail section on line 3-3 of Fig. 2. p

The reference numeral 4 designates a hollow member provided with piped openings 5 and 6. To the pipe 5 is attached a rubber, or other suitable material, hose 7, which. con meets with a suction device8 of any approved design. A. similar hose 9 or tubing is secured to the pipe 3 and carries a plurality of teat cups 10 of the usual pattern. The hollow member 4 is provided externally with an annular shoulder 11 adapted to be supported by a cover 12, provided with a central aperture 13 through which the member 4 is inserted so that the lower end thereof will project into a receptacle 14, closed by the cover 12, held in place upon the walls of lower open end 17 of the member 4 is cut upon'an angle and is provided with an external boss 18 provided with a bifurcated end 19 to which is pivoted an arm 20 carry-- ing a counterweight 21, upon one end, and in the other end having an aperture 22 through which extends a set screw 23 engaging a ball projection 24 carried by a plate 25 closing the open end of the memcollected within the member 4, the weight thereof will overcome the balancing action of the counterweight 21 and will open the' end of 'member 4 by depressing the plate 25,

thus allowing the milk to enter the receptacle 14.

The angular disposition of the plate 25 insures the complete draining of the mem-'.

ber 4, thus insuring sanitation. The ,pivoting of the plate 25 by means of the ball 24 cofiperating with the screw 23 insures at all times the proper seating of the plate 25 to close the member 4.

While the device has been shown as applied to a milking device using teat cups, it is obvious that a catheter machine would also cooperate therewith.

The invention as described herein is ad vantageously adapted to perform the function desired, but it is not my intention to limit myself to the specific construction shown and described, but to construe the claims as broadly as the state of the prior art will permit.

What I claim is 1. In a milking apparatus, a receptacle having its bottom inclined and adapted to initially receive the milk drawn from the cow, aninclined flat valve closing on the inclined bottom of said receptacle, a pivoted arm earryingasaid valve, a weight on said arm adapted to hold said valve in closed position, the weight of the milk in said receptacle at predetermined periods being adaptan on;
